Invoice Maker: Billing App

Invoice Maker turns your phone into a billing app. Add the client, the line items, a tax rate, and share a clean PDF invoice in under a minute — no account, no internet.

Built for the people who bill on the move: freelancers, sole traders, contractors, tutors, cleaners, photographers and small business owners who need an invoice app that opens fast and gets out of the way.

WHAT YOU GET
• Line items with description, quantity and unit price
• Subtotal, tax rate in percent and total calculated for you
• Invoice number and date on every document
• Your business details saved once and reused on every invoice
• Client block with address, email and Tax ID / VAT number
• Any currency symbol you like
• Notes at the bottom for payment terms or a thank-you
• Share the PDF by email, WhatsApp or any app on your phone
• Works fully offline — nothing leaves your device

HOW IT WORKS
Open Settings once and fill in your business name, address and tax number. Then tap +, enter who you are billing, add your items, set the tax rate, and hit Share PDF. The invoice is saved in the list so you can reopen, edit or resend it later.

WHY PEOPLE KEEP IT
Most billing apps for Android ask you to register, then hide the export behind a wall. This one is a straightforward invoice generator: your invoices live on your device, the PDF is yours, and there is no cap on how many you create.

Note: this is a document generator that produces a PDF invoice. It does not connect to any tax authority and does not file anything on your behalf.

PRO
Pro is optional and only removes the ads. Making invoices and exporting the PDF is never limited.

PRO SUBSCRIPTION
The core tools stay available without paying. Pro starts with a 7-day free trial, and ads keep showing during that trial. After it ends, the weekly subscription renews automatically and removes the ads. Cancel any time in Google Play.

If you already bought the Pro version, it stays yours for life, with no subscription.
